Car wont stop going rich
I posted a thread a while back about how my car would randomly go rich under very slight load. It used to only happen once and a while but now when the car is warmed up it will sometimes do it maybe once a minute and sometimes every 3 seconds. It goes from stoich right down to like 13.5 or lower and on the scanner it shows a commanded 13.5 AFR when that happens. I just replaced the primary O2 sensor and it didnt help. I dont like driving the car like this since I have to let off the car so much and as you can imagine the fuel mileage **** the bed. If I go WOT it is just fine or anything above about 50% throttle I guess, but under light load it happens. Anyone hear of this happening or had it happen to them? Im really lost and would like to just be able to drive my car normal!
Thanks in advance

Yeah me too man. Oh forgot to mention the 13.5 afr is converted to gasoline afr. Im not running that lean on E lol
Im thinkin maybe i should try tuning VE to see if that takes care of it. Maybe just under light load under 4k rpms or something
